How to use the AdHoc Dial feature, aka (PLAR)

Adhoc Number or Private-line automatic ringdown (PLAR): Adhoc/PLAR circuits have statically configured endpoints and do not require the user dialing to connect calls.

• The adhocNumber is dialed as soon as the Phone is taken off-hook or when the new-call button is pressed
• The adhocNumber will not be dialed when choosing a line; so when you choose a line you can enter a number manually. You can also enter the number in on-hook mode and then select the line (using enbloc dialing).

For example by adding this to the line configuration: adhocNumber = 818

Will automatically dial 818 as soon as the Receiver is picked up or the new call button is pressed. The behaviour is very similar to hotline, but on a per line basis.

Example of emergency phone in an elevator:

[SEP00ABC0006901]       ; emergency phone in elevator car 1
type=device
...
button=line,emergency
setvar=elevator_no=1    ; this variable will be available in the dialplan, so we know which elevator car we are dealing with.

[SEP00ABC0006902]       ; emergency phone in elevator car 2
type=device
...
button=line,emergency
setvar=elevator_no=2    ; this variable will be available in the dialplan, so we know which elevator car we are dealing with.

[emergency]
type=line
cid_name=elevator
cid_number=61112
...
adhocNumber=211        ; this is the extension that will be dialed when you go offhook.
...
setvar=emergencyline=yes
setvar=priority=high
